Overview:
The process for prepping single vent sound sash.

Definitions:

• SV: Window that operates horizontally.
• SH: Window that operates vertically.
• Sash Cap: A part that attaches to the sash and catches the balance springs to support the vent in an SH window.
• Rollers: The wheels put into the bottom of an SV window to allow the vent to slide horizontally.
• Interlock: The sash rail that connects with the mullion.
• Cam Lock: A lock with a cam mechanism that is engaged with a lever.
• Pak Lock: A lock that engages automatically when closed all the way.
• Vent Left: The closed vent will be on the left from the outside.
• Vent Right: The closed vent will be on the right from the outside.
   
  Procedure:

1. Find all the three-sash needed for the final window.

   2. Secondary VT
   3. Primary VT
2. Prep the sash in this order (Sec DL, Sec VT, Primary VT)
3. Check the sash label on the primary vent for the proper orientation of the unit.
   1. The Primary and Secondary VT will follow the orientation listed on the label.
   2. The secondary DL will be the opposite orientation of the two sash.
